Isolation and characterization of native microorganism from Turkish lignite and usability at fungal desulphurization
(Elsevier Sci LTD, 2014)
In this study, microorganisms were isolated from Mihaliccik region (Eskisehir, Turkey) lignites with low rank and high ash and sulphur content. A series of heavy liquids (from 1.3 g/ml to 1.9 g/ml) were used to determine ...
Evaluation of combined lignite cleaning processes, flotation and microbial treatment, and its modelling by Box Behnken methodology
(Elsevier Sci LTD, 2017)
In this study, first, the physicochemical cleaning of Cayirhan region's low-quality lignites was investigated by flotation to reduce ash content. In the flotation experiments, the effects of collector dosage, frother dosage, ...
Physical and physicochemical cleaning of lignite and the effect of cleaning on biodesulfurization
(Elsevier Sci LTD, 2014)
In this work, physical, physicochemical and biological processes were combined to decrease the sulfur and ash content of finely ground coal. Two separation methods - flotation and a multigravity separator (MGS) - were ...
Recycling of coal combustion wastes
(SAGE Publications LTD, 2009)
The separation of unburned carbon from coal-fired power plant bottom ashes was conducted in order to increase the possibility of the recycling of coal combustion wastes. A two-stage flotation technique was used for this ...
Conversion of coal-fired bottom ash to fuel and construction materials
(Taylor & Francis LTD, 2017)
In this study, solid wastes taken from Seyitomer coal-fired power plant bottom ashes were subjected to experimental research to obtain a carbon-rich fraction. The possible recycling opportunities of remaining inorganic ...
Floatability of Eskisehir Koyunagili Region Lignite Fines
(Int Scientific Conference Sgem, 2010)
In this work, samples were taken from Koyunagili Lignites Company Washing Plant feed and were subjected to extensive research to determine the floatability of lignite fines. The optimum conditions of flotation were determined ...
The Utilization of Unsaleable Lignite Fines at Eskisehir Koyunagili Region Lignite Deposits
(Taylor & Francis Inc, 2012)
Samples taken from stock piles of Koyunagili Lignites Company preparation plant were cleaned by means of gravity methods to obtain a saleable product. The optimum conditions of separation were determined under the laboratory ...
Determination of synergetic effect in co-pyrolysis of lignite and waste tyre
(Elsevier Sci LTD, 2015)
An attempt was made to investigate potential synergistic activities between waste tyre and lignite during co-pyrolysis. The parameters such as blending ratios of waste tyre and lignite, final pyrolysis temperature, heating ...
Effects of wollastonite and barite on the physical properties of a ceramic body
(Techna Srl, 2004)
Ceramic Factory, located Mid-West of Turkey, produces wall,and floor tiles. The factory recipe consists mainly of clay, pegmatite, quartz, albite and calcite. Wollastonite and barite were introduced into the factory recipe ...
Contact angle measurements on lignite surface
(2010)
Froth flotation has been widely used for cleaning and desulfurisation of coals for many decades all over the world. There is a close relationship between floatability of minerals and contact angle. Therefore surface ...
